Introduction of WNS Series Firetube Boilers

WNS series firetube boilers adopt a horizontal three-pass wet-back structure with a large furnace chamber design, ensuring complete combustion and achieving a thermal efficiency of over 98%. Equipped with an advanced fully automatic combustion control system, these boilers enable intelligent load adjustment, ensuring safe and stable operation. Additionally, WNS series firetube boilers feature a corrugated furnace and high-efficiency threaded smoke tubes, enhancing heat transfer, improving steam quality, reducing heating time, and increasing overall operational efficiency. In terms of environmental performance, WNS series firetube boilers can be equipped with low-NOx burners, reducing NOx emissions to below 30mg/Nm³, meeting global environmental standards. Furthermore, these boilers use high-quality insulation materials, effectively minimizing heat loss and improving energy efficiency.
